Abstract
Una copia (A) define a una campana (C) teniendo una pared cilíndrica (40) de el mismo diámetro interior que el diámetro exterior de los picos (22) de una tramo de tubería corrugada (B). La tubería corrugada incluye un empaque (30) que se recibe en el valle (24) cerca de la terminal del mismo. El empaque incluye una porción con pestaña (32) la cual es comprimida hacia el valle por la pared lateral (40) hasta que la terminal de la tubería se desliza dentro del cople (A). El cople incluye una ranura anular (44) la cual está en alineación con la junta cuando la terminal interior del tubo se empotra a un tope (10). La pestaña es empujada elásticamente hacia afuera dentro de la ranura (44) en donde una superficie (46) de empotramiento de ranura orientada hacia afuera, de la junta, empotra una superficie (48) de empotramiento de junta orientado hacia adentro, de la ranura. La junta puede incluir una porción de hule (52) de medición durométrica superior, más rígida, para empujar la pestaña más rígidamente dentro de la ranura y transferir carga axial hacia la campana, más rígidamente.
